Default Turnigy Nanotech 5000 1st cell at 1.3V

Ater having this lipo at a storage voltage of 3.8V per cell for about 3 months, I decided I would charge it up and fly since it was a cozy 32 degrees here. After hooking it up to the charger, it showed that the first cell was at 1.3 volts while the others where somewhere around 3.6/3.7V. Is this lipo reviveable? If not, I'm taking it out to the country with my AK-47 to put it down.

That is way out of whack. I think you'll be pulling an Ol' Yeller with it.

Yep, your pack is toast, put it out of it's misery. Between Zippy and Turnigy batteries I've had about 70% good packs, 30% bad. But, it is still way cheaper than high end brands even with a few bad packs.

I'd save the other cells if revival on cell 1 failed. Revival has never failed me...
